Abstract

An electronic article surveillance tag is described, in which a resonant circuit tuned to be detectable by a sensor is fabricated onto the upper and lower surfaces of a dielectric substrate. The dielectric substrate includes a membrane that provides insulation between a first circuit component fabricated onto the upper surface of the dielectric substrate and a second circuit component fabricated onto the lower surface of the dielectric substrate. When a deactivation voltage is applied across the electronic article surveillance tag, the membrane fails, causing the resonant circuit to become detuned.
